Problem in Big Box: M3 games don't accept the "exit" button

[Alex F.]

And this problem is persisting:

All games (M2, DEMUL, MAME) can be terminated with a mapped Big Box button which takes me back to the game selection menu. Only M3 games don't accept my "Back" button (Lost World, Ocean Hunter, Star Wars Arcade).

When I push the ESC button on my keyboard it works! 😕

Any help is greatly appreciated!
